Here's a super cute blog template with your own navigation bar. The "home" link is already working, and there are instructions in the code, but here's how to add your own links:
- Log into blogger. Click on "EDIT HTML"
- Scroll down the large box of code until you see the following (it's near the end)
<li><a href="'/'">Home</a></li>
<li><a href="'#'">Link Here</a></li>
<li><a href="'#'">Link Here</a></li>
<li><a href="'#'">Link Here</a></li>
To add your own links:
replace the "#" symbol with your link URL and then edit the "Link Here" text to be the name of your link (see colour coding below). So if you wanted to put a link back to me, this is what you'd change one of the lines to be:
<li><a href="'http://www.yummylolly.com'">Yummy Lolly</a></li>
You can remove or add any lines as you wish. You just have to add them before the </ul> code.
Let me know if you have any questions.

The design works with "new" blogger - ie: it's an XML template. Please ensure that you backup your widget data, as installing a new template will wipe/erase your current widget content.
